this must be a legit call if it comes from bitcoin vietnam, the true pioneer company based in saigon.
baba's kitchen always served great food and hosted many bitcoin meetups, so it is well known in the bitcoin community of saigon.

i can vouch for both companies, they are real people living and working in saigon who know best what is needed in the current situation.

if you support their efforts you would send your satoshis to the right people.

best of luck / stay strong vietnam!
